2. What is the process?

The first step involves grinding the concrete to reveal the aggregate within. The degree of uniformity of exposure needs to be specified. Once a satisfactory level of aggregate exposure is achieved, the concrete is polished using progressively finer grinding pads, then the last step is to polish the concrete with very fine diamond polishing pads???
